High Precision Custom Machined Brass Knurled Insert and Turning Tapping Brass Knurl Nut for Embedded Fastening

This knurled brass insert nut is manufactured from EU standard brass raw material and processed through multiple precision procedures including turning, drilling, knurling, and tapping. With strict dimension control, the tolerance reaches ±0.005 mm and surface roughness Ra1.6. It is primarily used as a threaded insert for injection molding, providing stable and durable threaded connections for plastic housings. Non-standard customization of different sizes and specifications is available.

• Raw Material: EU standard brass — stable material performance, good conductivity and corrosion resistance.
• Machining Process: Multi-process machining of turning, drilling, knurling, and tapping.
• High Precision: Dimensional tolerance ±0.005 mm, surface roughness Ra1.6.
• Knurled Structure: Anti-slip knurl pattern, not easy to loosen after embedding into plastic.
• Excellent Thread: Neat and clear tapped thread, smooth screwing and high pull-out resistance.
• Customizable: Support customization by drawings or samples to meet various assembly requirements.
